Net sales for the first quarter 2017 was $530,000 compared to $163,000 in the first quarter of 2016. The increase was driven by capital sales of the Accelerate Pheno(TM) system in the United States and sales of the Accelerate PhenoTest(TM) BC kit across the U.S. and Europe.

"We're excited to see this early momentum as it confirms the need for faster, more complete answers in the fight for life against serious infections," said Lawrence Mehren, President and CEO. "While there is more work to be done, we believe the initial uptake of the system sets us apart from recent IVD launches in microbiology."

The company was also awarded a public tender certification to supply its solution to Union des Groupements d'Achats Publics (UGAP), the largest public hospital purchasing group in France. The certification allows all French public hospitals access to acquire the system without additional tenders.

President and Chief Executive Officer, Lawrence Mehren, and Chief Financial Officer, Steve Reichling, will host a conference call to review the results at 4:15 p.m. Eastern Time on May 3, 2017.
